Solve for x.

Answer:
22.5
Step-by-step explanation:
Everything equals 180. This means that the 90 degree angle creates half of that would mean that everything on the right side of the 90 degree angle, also has to equal 90 degrees. X=22.5 because you have to combine like terms meaning x + 3x = 90- 4x=90. Divide by 4 on both sides of the equals sign. Plug that into a calculator and you get 22.5 Since it is only asking for the singular x, you don't have to solve for 3x. (It would be 67.5)
please help with these two!!!

Change 2x-y=-4 into slope-intercept form with steps
Answer:
y=2x - 4
Step-by-step explanation:
slope intercept is y = mx+b, where m is slope and b is y intercept.
subtract 2x from both sides of the equation
-y = 4 - 2x
multiply each term in -y = 4 - 2x by -1
(-y) . -1 = 4 . -1 + (-2x) . -1
y= 4. -1 + (-2x) . -1
simplify
y= -4 + 2x
Reorder
y= 2x - 4

1. Anil runs around a square park of side 90 m. Rohan runs around a rectangular
park with length 50 m and breadth 40 m. Who runs more and by how much?
Pls Help ASAP Pls
Answer:
Anil runs more by 180m.
Step-by-step explanation:
Given that:
Length of side of square park = 90 m
We will find the perimeter.
Perimeter = 4s
Perimeter = 4(90) = 360 m
Measurements of rectangular parks = length 50 m and width 40 m
Perimeter = 2(Length + Width)
Perimeter = 2(50+40) = 2(90) = 180 m
360 m > 180m
Difference = 360 - 180 = 180 m
Hence,
Anil runs more by 180m.

Answer:
180-118= 62
Answer is angle E= 62
Step-by-step explanation:
Vertical opposite angle of 118 is 118
So, we found out the interior angle. And sum of interior angles is 180. So you subtract 118 from 180 to get angle E.
Hope this helps!!!
Answer:
E is 62
Step-by-step explanation:
First find any angle relationships with the angle 118.
You can see that 118 can go next to E (corresponding angles).
That is a straight line, so in total it will 180 degrees.
180-118 would be E.
180-118 is 62.

Write the equation of the function of a parabola with vertex at (–1,–2) and a point (1,–6) that lies on the curve.
Question 9 options:
f(x) = −(x − 1)2 − 2
f(x) = −(x + 1)2 − 2
f(x) = (x + 1)2 – 2
f(x) = (x − 1)2 − 2
Answer:
The second answer is the correct one, f(x) = -(x + 1)² - 2
Step-by-step explanation:
We know that the answer must either be the second or third, because those two have (x + 1) squared, which means that the vertex must have an x co-ordinate of -1.
We also know that the third one can't be correct, as the y-coordinate of -6 requires a negative coefficient of the x^2. Without that the parabola would be moving upward from its vertex of (-1, -2).
With those we can eliminate all answers but the second one

Step-by-step explanation: The hint is in the table where the rows highlighted in pink, multiples of 5 and 8, contain the values of the original given ratio, 10:16
Equivalent ratios include any of the corresponding values in columns AND that are in the pink rows.
5:8, 10:16, 15:24, 20:32 . . .
We can see the pattern; pairs of multiples of the factors of the numbers in the original ratio are equivalent ratios.

Find the values of x and y.
2x 28 4y 28
Answer:
y=7
x°=15°
Step-by-step explanation:
First we see that there is a equilateral triangle (all angles and also sides should be equal to each other) meaning that 4y=28, which simplifies to y=7
Additionally, we can see that one of the acute angles of the equilateral triange is complementary with the 2x° angle, so 2x°+(the acute angle)=90°
Since the triangle is equilateral each angle must be equivalent and since there is only 180° in a triangle each angle is 180°/3=60°
so 2x°+(60°)=90°
simplify for x°
2x°=30°
x°=15°

Answer:
The answer is 2.3 B It is just by dividing
Answer:
B. 2.3
Step-by-step explanation:
Change the divisor 4.4 to a whole number by moving the decimal point 1 place to the right. Then move the decimal point in the dividend the same, 1 place to the right.
We then have the equations:
101.2 ÷ 44 = 2.3

A ski lift makes a 35° angle of elevation with the ground and takes passengers on a 6,550-foot ride up a mountain. Charlotte needs to figure out the elevation of the lift. Which equation and diagram can be used to model this problem?
Answer:
Top right one is the answer
Step-by-step explanation:
B :)
The elevation of the lift is equivalent to 11293.1 ft.
What is the angle of elevation?The angle of elevation is an angle that is formed between the horizontal line and the line of sight.
Given is that a ski lift makes a 35° angle of elevation with the ground and takes passengers on a 6,550 foot ride up a mountain.
Assume the elevation to be [x] ft. We can find the elevation as -
sin (35°) = (6550/x)
x = {6550/sin(35°)}
x = (6550/0.58)
x = 11293.1 ft
Therefore, the elevation of the lift is equivalent to 11293.1 ft.
